This invention relates to doors, and has for its object to provide an improved construction of door, together with an improved method of fixing doors in position. 18 The method of fixing a door in position, ac-

cording to the present invention, consists in clamping .the door assembly or the door frame to the wall in such a way as to secure the door tightly in position by pressure alone.

According to the present invention the door assembly may be made complete in two parts, the operation of connecting the two parts together causing the door assembly to grip tightly by pressure alone on the Wall. The door assembly according to the present invention may include the door frame made in two or more parts, in which case the door may be hinged to one of the said parts.

In a preferred way of carrying out the invention, the door frame comprises two angle portions, the adjacent longitudinal edges of which are adapted, when the unit is being assembled, to be drawn together by mechanical 25 means thereby causing the remaining limbs of the angle members to be pressed tightly against the sides of the wall adjacent the opening in the wall.

The lnvention will be illustrated, by way of example, with reference to the accompanyindrawings, wherein ig. 1 is a sectional plan of one form of door made accordingto the present invention, and

Fi s. 2 and 3 are elevations on the line A-. Fig. 1 respectively.

Fig. 4 is a sectional plan of another form of door made according to the present invention,

Fig. 5 is a section on the line 5 5, Fi 4.

Fig. 6 is a sectional plan of another orm of door made according to the present invention.

Fig. 7 is a view illustrating a further modiication.

Referring to Figs. 1 to 3, the door frame comprises two angle portions made up of moulding a, a and strips of wood b, b respectively, each air of members being rigidly connected toget er by bolts c, c. The member b is provlded with a longitudinal tongued extension d adapted to engage in a correg has a cut-away portion p, and three turned only. Thev bolt sponding recess e in the member b.

the parts are held securely in position by the pawl and ratchet `devicela'n.i It will be seen that the door assembly is held on to the wall by pressure between the members a, a and the wall. I E? In the form'shown in Figs. 4- and 5 ylike partsv are referred toby like letters of ref- L" erence. In this construction the plates g and Z are of different construction The plate down portions forming teeth'g, Qq. In g this case, the tongue d uis force into thef recess e likewise by means ofacrampyand whilst the cramp` is'in position, a threaded f bolt 1' is screwed intoandthroughthe mem- .ber b', andthe platel thereby causing the be forced intopthe material of b', thus holding the doorfiirinly in its assembled position, in whichagainthe door e5 is held in position Vby "pressure,'oxithe wall 1' may counter sunk, the head1 being hidden'vfrom viewb a pelletl of W0o In the lform shown; infFigLf, the recess c and tongue 'd are of peculiar construction having long and short co-acting sides. The long side of the slot c is provided with a cani surface a', and the design is such that on screwing the parts b, b together by means ofthe screw t, the member a is caused to leave the position indicated by dotted linesand to abut with great pressure against the wall. This consti-notional form indicates a very simple way of carrying out the invention. i

In the form shown in Fig. 7 plate 10 is screwed on one angle melnber and is provided for part of the way along the top edge with teeth 11 which are adapted to engage with teeth 12 on a second plate 13 ivotally connected on the other angle mem er. One end 14 of the plate 13 is rounded so that on forcing the two angle members together the end 14 is raised and the teeth 12 on the plate 13 can over-ride teeth 11 on the plate 10. When the angle members have been forced together as much as desired, the plate 13 drops by gravity so that the teeth 12 and 14 come into engagement and hold the two members firmly together.

In all forms shown in the drawings, the door assembly comprises only two parts, namely the angle members a, a', and b, b', the door being hinged to one of the angle members, and being already fitted with locks and other necessary fittings when the doors are brought to the site. The joints c, c are so designedr as to afford ample covering for any variation in thickness of plaster.

With doors made as above described, the hitherto considerable labour of plumbing, securing and fixing ground pieces, door linings or jambs, together with the necessary packing and counter wedging is entirely eliminated. Theinvention further allows of considerable latitude in the preparation of the door opening in the wall, and will cover roughness in the building up of the face of the opening as well as allowing for variation in thickness of bricks and plastering.

What I claim and desire to secure by Letters Patent is 1. Method of fixing doors in position consisting in making the door frame in two L- shaped parts and pressing the two parts together in a direction perpendicular to the wall with their inner edges against each other the outer edges of the parts in position against the wall by pressure alone.

3. A door frame comprising two L-shaped parts, inner and outer edges to each of said parts, a tongue and groove connection between the said inner edges and ratchet devices associated with the inner edges of the Leshaped parts which positively lock the outer edges of the parts in position against the wall by pressure alone.

In testimony whereof, I aix my si ature.

and their outer edges against the wall and positively locking the parts together along the contacting inner edges so that the outer edges are held in position against the wall by pressure alone.

2. A door frame comprising parts, inner and outer edges to each of said parts, a tongue and groove connection be.-

tween the said inner edges and positive locking means associated with the inner edges of the L-shaped parts which positively lock two L-shaped
